Experience, Prevalence, and Severity of Dental Caries in Mexican Preschool and School-Aged Children.

Objective Dental caries in Mexico continues to be a public health problem, indicated by it is high prevalence and incidence in children. This disease is associated with pain in preschool and school children, with large-scale consequences for the individual, society, and health systems. The objective of the present study was to determine the experience (mean of caries indices), prevalence, and severity of caries in children 2-12 years of age who sought dental care at a dental school in Mexico. Material and methods A cross-sectional study was carried out on 826 clinical records of patients ages 2-12 years. The dependent variable was caries, in terms of experience (mean primary teeth (dmft) and permanent teeth (DMFT) indices), prevalence (dmft and DMFT greater than 0), and severity (cutoffs of caries indices at various levels). The independent variables were age and sex. The data were analyzed in Stata 14 (StataCorp LLC, College Station, Texas). Results The average age was 7.2±2.3; 52.4% were boys. In the primary dentition, the caries experience (mean dmft) was 3.01±3.30, the prevalence of caries was 65.8%, and the severity dmft>3=37.3% and dmft>6=15.6%. In the permanent dentition, the caries experience (mean DMFT) was 0.99±1.88, the prevalence of caries was 31.5%, and the severity DMFT>3=12.5% ​​and DMFT>6=1.6%. The percentage of caries-free children in both dentitions was 26.1% (n=216/826). The experience, prevalence, and severity of caries were statistically different by age (p<0.001). Only in the severity of dmft>3 were differences observed across sex (p<0.05). Among children with mixed dentition, primary teeth were more affected than permanent teeth (2.46±2.87 vs 0.88±1.61; p<0.0001). Conclusions About seven out of 10 children were affected by cavities in either or both dentitions. It was observed that age was positively associated with dental caries, equally affecting girls and boys. In this sample, the primary dentition was impacted more than the permanent dentition. Despite being preventable, dental caries continues to be a health problem in children.

Ecological study on needs and cost of treatment for dental caries in schoolchildren aged 6, 12, and 15 years: Data from a national survey in Mexico.

To determine the treatment needs and the care index for dental caries in the primary dentition and permanent dentition of schoolchildren and to quantify the cost of care that would represent the treatment of dental caries in Mexico.A secondary analysis of data from the First National Caries Survey was conducted, which was a cross-sectional study conducted in the 32 states of Mexico. Based on dmft (average number of decayed, extracted, and filled teeth in the primary dentition) and DMFT (average number of decayed, extracted, and filled teeth in permanent dentition) information, a treatment needs index (TNI) and a caries care index (CI) were calculated.At age 6, the TNI for the primary dentition ranged from 81.7% to 99.5% and the CI ranged from 0.5% to 17.6%. In the permanent dentition, the TNI ranged from 58.8% to 100%, and the CI ranged from 0.0% to 41.2%. At age 12, the TNI ranged from 55.4% to 93.4%, and the CI ranged from 6.5% to 43.4%. At age 15, the TNI ranged from 50.4% to 98.4%, and the CI ranged from 1.4% to 48.3%. The total cost of treatment at 6 years of age was estimated to range from a purchasing power parity (PPP) of USD $49.1 to 287.7 million in the primary dentition, and from a PPP of USD $3.7 to 24 million in the permanent dentition. For the treatment of the permanent dentition of 12-year-olds, the PPP ranged from USD $13.3 to 85.4 million. The estimated cost of treatment of the permanent dentition of the 15-year-olds ranged from a PPP of USD $10.9 to 70.3 million. The total estimated cost of caries treatment ranged from a PPP of USD $77.1 to 499.6 million, depending on the type of treatment and provider (public or private).High percentages of TNI for dental caries and low CI values were observed. The estimated costs associated with the treatment for caries have an impact because they represent a considerable percentage of the total health expenditure in Mexico.

Prevalence of and risk indicators for chronic periodontitis in males from Campeche, Mexico.

OBJECTIVE: Determining the prevalence, severity and extension of chronic periodontitis and identifying risk indicators amongst policemen in Campeche, Mexico, using an electron probe. MATERIALS AND METHODS: A cross-sectional study of a convenience sample of 161 men was conducted. A case of periodontitis was defined as a participant having clinical attachment loss in at least one (3) 4 mm site. Every periodontal site in the mouth was measured by a standardized periodontist using a Florida Probe System. STATA 8.2 was used for bivariate and multivariate statistical analysis, using logistic binary regression. RESULTS Mean age was 38.36+/-10.99 years. 23,622 periodontal sites were available for examination. Mean (SD) teeth and sites examined per person were 24.45+/-4.63 and 146.72+/-27.80, respectively. Periodontitis prevalence was 62.7%. Periodontitis severity was 2.9 mm and extent was 53.7%. Adjusted for alcohol intake, factors associated with periodontitis prevalence were being older ((3)35 years; OR=2.08; CI95%=1.05-4.10), smoking (current/former; OR=2.22; CI95%=1.06-4.77) and gingivitis (presence; OR=3.35; CI95%=1.34-8.42). CONCLUSIONS: Many study participants had poor periodontal conditions, with substantial overall prevalence of periodontitis. Older age, tobacco use and the presence of gingivitis were factors associated with periodontitis prevalence.

Edentulism among Mexican adults aged 35 years and older and associated factors.

We used National Performance Evaluation Survey data to estimate the prevalence and associated factors of edentulism among noninstitutionalized adults aged 35 years and older in Mexico. Statistically, the variables positively associated with edentulism were older age (odds ratio [OR]=1.08) and female gender (OR=1.79). Nonsmoking status (OR=0.70) and having a higher wealth index score (OR=0.72) were negatively associated. This information constitutes the first large-scale evaluation in Mexico for one of the World Health Organization's priority oral health problems.

Introducing a clinical-behavioural scoring system for children's oral hygiene.

OBJECTIVES: Developing and testing a clinical-behavioural scoring system for assessing children's oral hygiene. MATERIALS AND METHODS: One clinical variable (the presence of dental plaque, measured using Silness and Loe's index) and one behavioural variable (self-reported tooth brushing frequency) were combined into secondary data analysis of research databases for 3-6-year-olds and 6-13-year-olds in a Mexican community. The combined scoring is an ordinal scale that depicts suitable, moderate and inadequate hygiene. Blinded dental examiners also collected dmft/DMFT data in standardised conditions. Data was analysed with Spearman's rho, Kruskall-Wallis, non-parametric tests for trends and Pearson's chi2 tests. RESULTS: 1303 children aged 3-6 years old and 1644 children aged 6-13 years old participated in the study. Clear relationships existed between the combined scoring system and dmft (p < 0.01) and between the scoring system and DMFT (p < 0.01), suggesting that the combined clinical-behavioural scoring system is a reasonably accurate measurement of the relationship between caries experience and oral hygiene in children in the given setting. CONCLUSIONS: The combined clinical-behavioural scoring system is a simple, easy-to-use tool that incorporates clinical and behavioural data commonly found in dental systems. Whether the clinical-behavioural scoring system can be generalised remains to be established.

Objetivos: Desarrollar un sistema de puntaje clínico-conductual para medir la higiene bucal en niños. Material y Métodos La investigación se realizó en dos etapas: 1) detección y selección de componentes de la higiene bucal, y 2) evaluación de la asociación con la caries dental. Una variable clínica (presencia de placa dentobacteriana usando el índice de Silness y Lõe) y una variable conductual (reporte de la frecuencia de cepillado) fueron combinadas en un análisis secundario de dos bases de datos de investigaciones epidemiológicas en niños de 3-6 años y de 6-13 años de edad en una comunidad mexicana. El puntaje combinado es en una escala ordinal que describe higiene bucal adecuada, moderada e inadecuada. Los examinadores también colectaron los índices ceod/CPOD. Los datos se analizaron con las pruebas de rho de Spearman, Kruskall-Wallis, no-paramétrica para tendencias, y ji2 de Pearson. Resultados 1 303 niños de 3-6 años de edad, y 1 644 niños de 6-13 años de edad participaron en los estudios. Se encontró una lara relación entre el sistema y el índice ceod (p<0.01), y entre el sistema y el índice CPOD (p<0.01), sugiriendo que este sistema es una medida adecuada de la higiene bucal en esta población. Conclusión El sistema de puntaje clínico-conductual para medir la higiene bucal es una herramienta simple y fácil de usar que incorpora datos clínicos y conductuales comúnmente encontrados en investigaciones dentales. El potencial del sistema de puntaje clínico-conductual para medir la higiene bucal para usarse en otras poblaciones necesita establecerse en estudios subsecuentes.

Caries increment in the permanent dentition of Mexican children in relation to prior caries experience on permanent and primary dentitions.

OBJECTIVE: To evaluate the likelihood of caries increment in schoolchildren, based on their prior caries experience. MATERIAL AND METHODS: We undertook a longitudinal study in 452 six-to-nine year olds between 1999 and 2001 in Mexico, with dental exams conducted by two standardized examiners (kappa>0.85). The dependent variable was the DMFT increment, dichotomized as without increment, and at least one unit of increment. Independent variables estimated caries experience at baseline. Data were analyzed using non-parametric tests and generalized linear models (log-binomial) to calculate relative risk (RR) adjusted for age and sex. RESULTS: The percentage of caries-free children diminished by 20.5% from 1999 to 2001. DMFT index increased two-fold, from 0.25+/-0.70 in 1999 to 0.77+/-1.30 in 2001 (p<0.001). The overall risk for this sample was 24%. The DMFT increment was higher (p<0.001) in children with DMFT>0 and dmft>0 in 1999 (RR=1.89, 95% CI=1.37-2.62; RR=2.71, 95% CI=1.94-3.76, respectively). The likelihood for DMFT increment from the 1999 levels was: (1) 2.78 times higher (95% CI=2.06-3.76) if schoolchildren had caries in any of the first permanent molars and (2) 1.62 times higher (95% CI=1.20-2.19) if schoolchildren were affected by high severity caries at baseline. CONCLUSIONS: Both caries prevalence and mean DMFT had significant increments in 18 months. Dental caries in the primary (dmft) and permanent (DMFT) dentitions at baseline are goods indicators of subsequent caries development in this group of children in a medium income country. This relationship became stronger when the occurrence of caries in the first permanent molars was included.

Dental attrition and associated factors in adolescents 14 to 19 years of age: a pilot study.

PURPOSE: This cross-sectional study evaluated the relationship between attrition and diverse variables in 390 Mexican adolescents aged 14 to 19 years. MATERIALS AND METHODS: An ordinal scoring system was used to describe the severity of attrition. RESULTS: Attrition prevalence was 33.3% and was associated with older age, presence of defective restorations, Class II malocclusion, and perception of stress level. CONCLUSION: Our results suggest that attrition is present in 1 of every 3 adolescents.
